Typing input to angle slider does not work

It does not accept input in whole degrees, which is counterintuitive. Check a value less than 360 degrees by clicking on it, you see it'll be on the low side. Radians?

Testing.

Inputting 1 gives a 57 degree angle.
2 gives 115.
3 gives 172.
4 gives 229
5 gives 286
6 gives 344

360 (manually reduced and increased) returns 6.28.

So while it's consistent, not sure what is up. Dur me blind.

Other way round
100 degrees gives 1.74.
200 degrees gives 3.49
300 degrees gives 5.23+ (remains at 300 through two clicks, returns 5.23 and 5.24)
45 degrees gives 0.78
90 degrees gives 1.57
180 degrees gives 3.14+ (remains at 180 through two clicks, returns 3.14 and 3.15)

Conclusion:
360 is 2xPi. Enter in radians, outputs degrees.

Prolly needs a tooltip mentioning this? At the very least.
